Police in Quincy are trying to shut down an event at a club after problems with the club drug "Molly."

Police said they've responded to 12 overdoses at the Ocean Club in Marina Bay this summer. In the past three weeks, they said that 10 people were arrested and accused of selling selling "Molly," a name for the drug MDMA or Ecstasy.

"I think what it is, this venue out there hosts these rave-type parties with out of town DJs -- big DJs -- and it attracts the crowd that is prone to use 'Molly,'" said Quincy Police Chief Paul Keenan.

Police said detectives have been using a handheld device to analyze drugs at the venue and said that they commonly find "Molly."

Officers will meet with management Thursday to try to cancel an event at the club later this month, citing a public safety concern.
